A cat-loving Manhattan dominatrix who goes by the name of Goddess Haley is proving that sometimes abuse can be a good thing, as she uses the proceeds from her meet-and-beat sessions to save neglected felines.

While working full time torturing willing men at an S&M dungeon in Chelsea, Haley has become the Mother Teresa of masochism by running a cat shelter out of her Brooklyn apartment in her spare time.

The 28-year-old says that caring for the cats often leaves her beat.

“It’s kind of funny. I spend all day as the master of men, but when I get home, I’m ruled by my cats,” said Haley, who asked that her real name not be used.

Haley and her husband, Andy, a 28-year-old musician from Kansas City, care for up to 30 cats at a time in their two-bedroom Bushwick apartment.

They found many of the cats on the street. In the last year, Haley has rescued, nursed and put up for adoption about 90 cats.

Haley works with the ASPCA in Brooklyn, veterinarian Daniel Giangola of Animal Health Care on the Upper East Side and Kittykind, a nonprofit cat-rescue group in Union Square.

The S&M “goddess” says she will go any length to fight for cats. That includes taking her day job, where she gets up to $180 an hour to abuse S&M aficionados.

She said she became a dominatrix when she moved to New York five years ago after she saw a job ad in a newspaper. She knew that it would be a perfect way to fund her rescue operations, which can cost as much as $1,000 a month, with $5,000 per year in vet bills.

“Being a dom is hard work – I’ve pulled muscles whipping slaves – but I do it because I earn enough to help a lot of cats,” she said.

Sometimes, her job and her cat-calling conflict, and she has to take her feline friends to work.

“Once, I was even flogging a slave and realized it was feeding time and had to excuse myself for a few minutes. But he probably liked the neglect,” she quipped. “But, really, some of the slaves are very understanding. Some know what I do, and they appreciate it.”

One animal-rights activist praised Haley for her work, although she warned about keeping such a large number of cats in a home.

“That’s a lot of cats for a two-bedroom, and I wouldn’t encourage anyone to do it,” said Sandra DeFeo, co-executive director of the Humane Society of New York. “But no animal is happy in the streets, [and] obviously, she works very hard to take care of them.”
